Comment (by gavekort):

 Can any documentation be found for write lock on the database ? I think
 i'm having similar problems. I have read throught the manuals but i cannot
 find what i'm looking for. Any material besides that available ?
 Sorry for my english.

 kind regards.

 This error generally means that something else has held a write lock on
 the database for too long. It's hard to tell from your logs what that
 might be - all of the queries that timed out are read-only queries
 (getBuildset and getBuildRequests).[http://www.nemgavekort.dk/l/gavekort-

 Does this still occur after a master restart? If so, can you try it with a
 clean state.sqlite file? (Just remove the file and run 'buildbot upgrade-
 master' again)
